Abstract: This invention relates to a spring fastener, which comprises side structures, preferably connected to form a U-shaped structure. The two side structures have multiple engagement springs comprising pairs of recesses and respective peaks. The number of these pairs is different on one spring than the number of pairs on the other springs. The spring fastener may further comprise an elastic or resilient body under the top end of the fastener, thus providing noise elimination or dampening. In a different embodiment, the fastener may also comprise rigid supports over the two extremities of its top end, which rigid supports force the resilient body all the way around on the fastened article, so that this configuration provides, in addition to noise elimination or dampening, excellent waterproofing properties.
